[c-nsp] LDP based CSC VPN - ASR9k/IOS-XR 4.3.4

[Arun Kumar]

Hi All,

I am trying to configure CSC MPLS VPN on IOS-XR 4.3.4 on ASR 9K as PE.
Currently the configuration is on NPE-G2 and NPE-G1 as PE routers.

LDP is configured between PE and CE for label exchange and OSPF is the
protocol between PE and CE.

When I try to configure LDP between ASR9K and CPE, I am not getting LDP as
the option between PE and CE, I am not getting any option of specifying LDP
 under the VRF.

Even the IOS-XR MPLS config guide only talks about BGP based label exchange
between PE and CE on IOS-XR.

I would like to confirm, can LDP be configured under VRF in ASR9K as PE or
BGP is the only option available?

thanks in advance
Arun
